I was astonished to see that Microsoft provided this software (R) under the terms of GNU GPLv2 or GNU GPLv3 explicitly (but not any later version)[0]. May be because this is a derivative work from GNU R.

That's a good news for free software developers. Microsoft GVFS[1] was using MIT (while git itself is GNU GPLv2) + some EULA[2]. May be they chose MIT for GVFS because GNU GPL license explicitly disallows additional restrictions (ie, EULA can't be added, otherwise it will tbe a violation of GNU GPL).

Edit: I see that the package is distributed as a single binary at https://mran.microsoft.com/download Which shall include (I haven't checked the contents) Microsoft R Open under GNU GPLv2 and Intel MKL with some EULA (ie, additional restrictions). Won't that be a violation of GNU GPLv2?
